FMEA AIAG & VDA Version:

AIAG & VDA Version

The Automotive Industry Action Group (AIAG) and the German Association of the Automotive Industry (VDA) joined forces to harmonize the FMEA methodologies used in the United States and Europe. The AIAG & VDA FMEA Handbook was first published in 2019 and represents the convergence of the two methodologies into one cohesive approach.

Key Features:

Seven-Step Approach: The AIAG & VDA version uses a seven-step approach, which adds more structure to the FMEA process. The steps are:

  1. Planning & Preparation
  2. Structure Analysis
  3. Function Analysis
  4. Failure Analysis
  5. Risk Analysis
  6. Optimization
  7. Results Documentation

Scoring System: It introduces a new scoring system that evaluates Severity, Occurrence, and Detection on a scale of 1 to 10, as opposed to the AIAG 4th Edition’s 1 to 5 scale.

Action Priority (AP): It replaces the traditional Risk Priority Number (RPN) with Action Priority levels of High (H), Medium (M), and Low (L).

Form Sheets: Detailed form sheets guide the user through the seven steps, making it easier to apply the methodology.

Focus on Prevention: The AIAG & VDA version puts more emphasis on preventive measures rather than just mitigating existing problems.

Greater Collaboration: The new methodology encourages a more collaborative approach, involving cross-functional teams in the FMEA process.

Enhanced Traceability: The process is designed to provide better traceability of the decisions made during the FMEA, which is valuable for audits and continuous improvement.

Relevance and Accuracy:

The AIAG & VDA version of PFMEA is highly relevant in today’s competitive and regulatory landscape, offering a more unified and structured approach to risk management. It is particularly beneficial for companies that operate in multiple regions, helping to standardize procedures.

The methodology is accurate in its representation of risk, offering a granular scoring system and action priority levels. This makes it a reliable tool for quality management and compliance.

Advantages and Challenges

Advantages:

Global Standardization: One of the most significant advantages is the move towards global standardization of the FMEA process, which can be particularly beneficial for multinational corporations.

Comprehensive Risk Assessment: The seven-step approach allows for a more thorough analysis, including preventive measures that focus on problem prevention rather than mere problem-solving.

Detailed Documentation: The methodology mandates robust documentation, which is helpful not only for internal review but also for regulatory compliance.

Resource Allocation: With the new Action Priority (AP) system, organizations can allocate resources more efficiently to areas with higher risks, thereby optimizing costs.

Challenges:

Learning Curve: Teams accustomed to older versions of FMEA will need to undergo training to understand the new seven-step process and scoring metrics.

Time-Consuming: The detailed nature of this approach can make the process more time-consuming compared to previous methodologies.

Compatibility: Older systems and documentation may need significant updating to align with the new methodology, which could be resource-intensive.

Quality Metrics Evaluation

Relevance: The AIAG & VDA PFMEA is highly relevant for organizations aiming to standardize their risk assessment processes across multiple locations and comply with international quality standards.

Accuracy: The methodology is designed to provide accurate assessments of risks, thanks to its granular scoring system and comprehensive seven-step approach.

Completeness: The approach is comprehensive, covering planning, analysis, and optimization, making it a complete tool for risk assessment.

Robustness: Its structured format and detailed documentation make it a robust tool for quality management and regulatory compliance.

Consistency: The methodology encourages consistency by standardizing the approach across different teams and regions.

Specificity: Its granular risk assessment allows for specific and targeted actions, contributing to improved process quality.
